Abstract

A multi view display (5) provides different viewing angles for different images (3, 4). The display (5) may comprise a single screen on which two or more images (3, 4) are interleaved, or a number of overlapping screens on which respective images (3, 4) are displayed. Viewing manipulation means such as privacy films or lenticular arrays control the viewing angles for each image (3, 4). The multiview display (5) may be used in a vehicle, to simultaneously display a movie (3) to a passenger (1), and a navigation image (3) to a driver (2).

Claims

1. A multi-component display comprising:

a first display screen comprising a first plurality of pixels, wherein said first display screen is operable to display a first image using said first plurality of pixels; and

a second display screen comprising a second plurality of pixels, wherein said second display screen is operable to display a second image using said second plurality of pixels, wherein said first and second display screens overlap, and wherein said second display screen is further operable to display said second image for viewing from a first viewing angle and contemporaneously for reducing visibility of said second image from a second viewing angle.

2. The multi-component display of claim 1, wherein said second display screen further comprises a third plurality of pixels, wherein said second display screen is further operable to display a third image using said third plurality of pixels, and wherein said second display screen is further operable to display said third image for viewing from said second viewing angle and further for reducing visibility of said third image from said first viewing angle.

3. The multi-component display of claim 2, wherein said second and third plurality of pixels are interlaced.

4. The multi-component display of claim 1 further comprising:

a first optical component for manipulating images displayed by said second display screen, wherein said first optical component is further operable to reduce visibility of said second image from said second viewing angle, and wherein said wherein said first optical component is further operable to reduce visibility of a third image from said first viewing angle.

5. The multi-component display of claim 4, wherein said first optical component is disposed between said first and second display screens.

6. The multi-component display of claim 4, wherein said first optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern.

7. The multi-component display of claim 1 further comprising:

a viewing angle enhancer for enabling viewing of said first image from said first and second viewing angles.

8. The multi-component display of claim 7, wherein said viewing angle enhancer is selected from a group consisting of a diffuser and a refractor.

9. A multi-component display comprising:

a first display screen comprising a first plurality of pixels, wherein said first display screen is operable to display a first image using said first plurality of pixels; and

a second display screen comprising a second plurality of pixels, wherein said second display screen is operable to display a second image using said second plurality of pixels, wherein said first and second display screens overlap; and

an optical component for manipulating images displayed by said second display screen, wherein said optical component is further operable to enable viewing of said second image from a first viewing angle and contemporaneously operable to reduce visibility of said second image from a second viewing angle, and wherein said optical component is disposed between said first and second display screens.

10. The multi-component display of claim 9, wherein said optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern.

11. The multi-component display of claim 9, wherein said second display screen further comprises a third plurality of pixels, wherein said second display screen is further operable to display a third image using said third plurality of pixels, and wherein said optical component is further operable to enable viewing of said third image from said second viewing angle, and wherein said optical component is further operable to reduce visibility of said third image from said first viewing angle.

12. The multi-component display of claim 11, wherein said second and third plurality of pixels are interlaced.

13. A multi-component display comprising:

a first display screen comprising a first plurality of pixels, wherein said first display screen is operable to display a first image using said first plurality of pixels; and

a second display screen comprising a second plurality of pixels, wherein said second display screen is operable to display a second image using said second plurality of pixels, wherein said first and second display screens overlap, wherein said second display screen is further operable to display said second image in a first plurality of regions of said second display screen, wherein said second display screen is further operable to display a third image in a second plurality of regions of said second display screen, wherein said first and second plurality of regions are interlaced, wherein said second image is visible from a first range of viewing angles, and wherein said third image is visible from a second range of viewing angles.

14. The multi-component display of claim 13, wherein said second range of viewing angles includes at least one viewing angle which is different from said first range of viewing angles.

15. The multi-component display of claim 13, wherein said second display screen further comprises a third plurality of pixels, and wherein said second display screen is further operable to display said third image using said third plurality of pixels.

16. The multi-component display of claim 15, wherein said third plurality of pixels are associated with said second plurality of regions and comprise directional pixels operable to reduce visibility of said third image from said first range of viewing angles, and wherein said second plurality of pixels are associated with said first plurality of regions and comprise directional pixels operable to reduce visibility of said second image from said second range of viewing angles.

17. The multi-component display of claim 13 further comprising:

a first optical component for manipulating images displayed by said second display screen, wherein said first optical component is further operable to reduce visibility of said second image from said second range of viewing angles, and wherein said wherein said first optical component is further operable to reduce visibility of said third image from said first range of viewing angles.

18. The multi-component display of claim 17, wherein said first optical component is disposed between said first and second display screens.

19. The multi-component display of claim 17, wherein said first optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern.

20. The multi-component display of claim 13 further comprising:

a viewing angle enhancer for enabling viewing of said first image from said first and second ranges of viewing angles.

21. The multi-component display of claim 20, wherein said viewing angle enhancer is selected from a group consisting of a diffuser and a refractor.
